Granted: 1903-03-05
Abstract: 28,214. Sprague, H. H. Dec. 22. Meters.-The meter consists of four parts, a central casing 1, two side covers 2, 3 secured to the central part by screws, and a hollow cap 5 forming a gas - distributing chamber 11. Two flexible diaphragms 6, 7, having central metal discs 43, 44, are secured to the central part by means of the side covers. Three measuring-chambers 8, 9, 10 are thereby formed, to which the gas enters by means of passages such as 15, 18, 19, and 16, 20, 21, the passages leading to the drawbar 9 not being shown in Fig. 2. Upon the flat top surface 1<a> of the body portion of the meter is mounted a valve seat 13, having a central discharge opening 24 bounded by the curved edges b<1>, c', d<1>, e', f<1>, g<1>, Fig. 7, and three outer inlet openings, bounded by the curved edges b, c, d, e, f, g. The edges b, b<1> are struck from the same centre b<2>, and similarly all the other edges from the centres c<2>, d<2>, e<2>, f<2>, g<2>. Above the openings is a circular valve 22, formed of glass and having an annular recess 29 leading the gas from the exhaust port 24 to an outlet tube. The valve is rotated by a pin 31 engaging in an opening in the under surface of the valve, the pin being formed on a crank 32 of a shaft 33 carried in bearings in a hanging bracket 34. The lower end of the shaft has a crank 33<1>, which is operated by the movements of the diaphragms. Each diaphragm is supported by, and caused to travel in a fixed path by, a rod 45, 46, hinged at one end to the central casing and at its other end journalled in ears 49, 50. The links 51, 52 connect the diaphragm to the crank 33<1>, the former directly. and the latter indirectly by means of an adjustable stud on a crank plate 54. The circular movements of the valve are carried to the indicating-mechanism by a projection 22<1> on the valve engaging a foot 40<1> of a vertical shaft 40 carrying a worm 41 engaging a pinion on a shaft 36 which is connected to the indicating-mechanism. The shaft 36 is supported by a frame 37 and by a partition 38 into which it screws. A stuffing-box gland 39 prevents escape of gas.

Title: Improvements in Nor-rotative Pumping Engines.
Inventor: AURIA LUIGI D
Filed: 1903-01-05
Granted: 1903-03-26
Abstract: 268. Auria, L. d'. Jan. 5. Governing or controlling pumps.-Relates to direct-acting non-rotative pumps of the kind described in Specification No. 2883, A.D. 1891. Expansive working is made possible by means of an improved compensating-device, which also allows of variation of the piston speed. A compensator piston, carried by the main pump rod, works in a cylinder 4, the opposite ends of which communicate with the two ends of a pipe 6. Liquid contained in the cylinder 4 and pipe 6 is put in motion during the first part of the stroke, and gives up its energy during the second part. The ends of the cylinder 4 are enlarged, and the piston is notched, as at 4<b>, so that, if the piston is carried beyond its normal stroke, the energy in the liquid column is rapidly exhausted by the passage of the liquid through the notches. In addition to the main pipe or byepass 6, there is fitted a smaller bye-pass 7 provided with a valve 9, by opening or closing which the piston speed is increased or diminished in accordance with a law stated in the Specification. The valve 9 is controlled by the delivery pressure or the like so as to regulate the speed of the pump in accordance with the demand. More than one bye-pass 7 may be used.

Patent GB-190303783-A (GB)
Title: Electric Light Safety Relay.
Inventor: JOHNSON ARTHUR HENRY
Filed: 1903-02-18
Granted: 1903-12-31
Abstract: 3783. Johnson, A. H., and Bircham, F. R. S. Feb. 18. Relays.-Consists in a relay for use in electric lighting, whereby, when the normal lamp partly or completely fails, it is cut out of the circuit and an auxiliary lamp automatically lighted. The current from the mains n, p passes round a circuit consisting of an eccentrically-mounted carbon disc g, a spring f normally resting on the disc, and an armature d, Figs. 1 and 5, then round an electromagnet m' and through the auxiliary lamp r. It also passes round a circuit containing an electromagnet m<1>, and the normal lamp s. The armature d is given a bias in favour of the attraction of a pole-piece c, by adjusting its distance from the pole or by regulating the relative ampÞre-turns on the magnets m<1>, m<2>, so that the contact c, k<1> is made when a current flows, thus lighting the lamp s, and breaking the circuit of the lamp r at the brush g. When the lamp s fails, the armature, no longer being attracted, swings over on us pivot e owing to the weight of the spring f, causing the contact f, g to be made and the lamp r to be lit. The magnet m<2> is excited at the same time, and the contact a, o closed by the attraction of the armature to the pole-piece, thereby firmly closing the circuit of the lamp r, while owing to the breaking of the contact k<1>, c, the lamp s is cut out of the circuit. When applied to an alternating-current circuit, the iron magnet core is laminated. The spring f may, in some cases, be adjusted so as normally to rest a slight distance off the carbon disc, thus only making contact through the resilience of the spring when the armature is released from the pole c. This construction is shown in Fig. 6, where a small weight V gives the necessary momentum and a spring x and a stop z serve to adjust the spring f.
Patent GB-190307591-A (GB)
Title: Improvements in Change and Reversing Gears.
Inventor: PARKIN JOSEPH WALTER
Filed: 1903-04-01
Granted: 1903-06-04
Abstract: 7591. Parkin, J. W., and Parkin, H. W. April 1. Toothed gearing.-Epicyclic gearing is arrangEd for driving a shaft forward at different speeds and for reversing it. The driving-shaft a carries the pinion b, fixed on it, and the wheels c, d, e, mounted on loose sleeves. The wheels b, c, d, e all gear with wheels h, i, j, k made integral and mounted on the spindle m carried by the shell g, g<1>. The shaft to be driven is connected with the wheel c through a chain-and sprocket wheel n or by other means. The sleeve of the wheel d carries the brake pulley d<2> fitted with the band brake d<3>. The sleeve of the wheel e carries the pulley e' fitted with the brake e<3> and forming part of a friction clutch f. The other member of the clutch is formed on the shell g', which is fitted with the brake g<2>. If the clutch f is engaged and the brakes d<3>, e<3>, g' are off, the whole apparatus rotates bodily, and the wheel c turns at the same speed as the shaft a. If the clutch f is disengaged and the brake g<2> is put on, the spindle m is held stationary, and the wheel c is driven at a reduced speed through the wheels b, i, h. A further reduction of speed is effected by throwing off the brake g and putting on the brake d<3>, the pinion d being then stationary, and the shell g<1> travelling round. When the brake d<3> is taken off and the brake c<3> put on, the shell g<1> moves at such a speed that the wheel c is driven backwards. To balance the apparatus, a second set of wheels h<1>, i<1>, j<1>, k<1> may be mounted on a spindle m<1>, and, in change gears of large diameter, three or more sets may be employed. If only two forward speeds are required, the wheel d and brake device d', d' are dispensed with. On the other hand, if more speeds are required, either forward or reverse, additional gears are introduced.

Patent GB-190312774-A (GB)
Title: Improvements in and relating to Pumps
Filed: 1903-06-06
Granted: 1903-12-03
Abstract: 12,774. Lake, H. H., [Southwark Foundry and Machine Co.]. June 6. Pump valve gear; gas-actuated pumps; governing or controlling pumps.-Relates to the actuation of pump valves, especially applicable in connection with air compressing or blowing engines, and is particularly adaptable to pumps actuated by gas engines. The admission valves are of the sliding gridiron type and are so connected with the engine as to move in a fixed relationship with the propelling piston of the pamp, and their closing can be retarded at will or automatically, so as to keep the work done per cycle constant, no matter how the pressure in the receiver may vary. Figs. 2 and 3 show a side elevation, and a transverse sectional end elevation, through the valve chambers, respectively, of the complete arrangement. Motion is communicated by the shaft G<2> from the crank shaft to the valves H of the gas engine and the blowing or compressing engine valves. This shaft actuates. through gear G', G', the eccentrics G<11>, G<12>. These eccentrics, as shown in Fig. 3, actuate the valve mechanism. J is the pump chamber, having receiving-chambers J<1> at each end, which are connected by the conduit J'. The chamber J is provided with admission and delivery ports and valves at both ends, as shown at k, l, and K L, Fig. 3, respectively. Rods L', K<1> transmit the motion from the link mechanisms to the valves. Figs. and 7 are detail views, showing bow the closing of the admission valves is regulated by the hand - wheel S<4>; the wheel S<7> is a clamping - wheel. Fig. 5 shows an arrangement for doing the same automatically. The cylinder W<3> is connected by the pipe j to the receiving-chambers J'. If the pressure in the chambers J<1> increases, the piston W<2> is forced back against the spring W<4>, and thus, by the link W, which is connected to the rocking bar Q, delays the closing of the admission valve. The pump thus. during part of the stroke, merely forces part of the air back through this valve, and hence, though the engine works against a higher pressure, the working stroke is less, and the work done consequently remains the same. Cylinder w<6> acts as a dash-pot. The delivery-valve rod L<1> is connected at its outer end to the piston T, which works in a cylinder connected by the pipe U<5> to the pump chamber J. When the pressure in the pump chamber is less than in the receiving- chambers, the delivery valve is pressed on to the ports ; when the pressures become almost the same, the friction between the valve and the ports decreases, with the result that the pressure on the piston T immediately opens the valve, thus working automatically at the correct moment. Fig. 8 shows, diagrammatically, the action of the valve mechanism and adjustments. The points x<2>, y' show that the point of opening the admission valve is constant, although the closing points x<1>, y<1> can be varied as desired.

Title: Improvements in or relating to Artificial Fuel and the Manufacture thereof.
Inventor: SHEDLOCK JAMES JOHN
Filed: 1903-10-03
Granted: 1904-09-29
Abstract: 21,300. Shedlock, J. J. Oct. 3. Moving-stirrer apparatus.-Coal, coke, or a mixture of these substances in a divided state is mixed with gas tar, astatki, or similar material, and pressed into blocks for fuel. Other materials, such as lime, may be added. The mixing is performed in a closed machine in which the materials are at the same time heated by circulation of superheated steam, carbon dioxide, or other inert gas, by which the volatile constituents are carried off, leaving a pitch-like adhesive coating on the solid particles. The hot gases are passed into condensers and are afterwards reheated, any loss by leakage being made up. One form of the mixing and moulding machinery is shown in section in Fig. 1. The coal and tar are fed from the hopper A and tank E on to a revolving cone, from which they are displaced by the fixed arms F on to the fixed cone G, from which they are delivered by arms H attached to the cone C into the mouth G<1> where, with the worm I, they form a seal. The materials then pass from the cone J through a series of openings in the plates K under the action of the scrapers L. The openings in the plates are spirally disposed, and the arms L are mounted loosely on the square shaft. The heated gas is admitted between the plates through the pipes 1 and passes through the condenser 6 and out by the pipe 11 to be re-heated. If steam is used, the water is removed through the pipe 7 and the distillates through the pipe 8.

Title: The Manufacture of o-nitro-o-amido-p-acetamidophenol and Dyestuffs therefrom.
Inventor: RANSFORD ROBERT BOLTON
Filed: 1903-11-10
Granted: 1904-09-22
Abstract: 24,409. Ransford, R. B., [Cassella & Co., L.]. Nov. 10. Di-o-nitro- and o-nitro-o-amido-p-acetamidophenol are obtained by energetically nitrating p-acetamidophenol, giving the dinitro body, and then reducing the latter with suitable reducing-agents, yielding the nitramine. For example, nitro-sulphuric acid is introduced, with cooling, into a solution of the amidophenol in sulphuric acid at 0‹ C., and, after standing for several hours, the dinitro compound is separated out by the addition of ice. It is filtered off, washed, transformed into the sodium salt, and introduced at 25‹ C. into a solution of sodium sulphide. After complete reduction, the product is separated by neutralization with hydrochloric acid and filtered off. The nitramine, when purified, is difficultly soluble in water, ether, and benzene, but easily so in glacial acetic acid, and crystallizes from alcohol in reddish-brown needles melting at 190‹ C. Dyes, artificial. - Diazotized o-nitro-o-amidop-acetamidophenol, on combination with amidonaphthol- or dioxynaphthalene-sulphonic acids yields dyes which dye wool level blue shades, changing to fast bluish-greens by chroming. Thus, for example, a soda solution of 1-8-amidonaphthol- 3-6-disulphonic acid is employed. After about twelve hours, the dye-stuff is salted out and filtered off.
